Description

    BACKGROUND
  • This disclosure relates to surgical drill guides. US 2015/282819 A1 discloses a staple holder and drill guide. The drill guide comprises: a handle including two openings; and two alignment tubes each having a substantially cylindrical shape and including a body that defines a drill passage that aligns with one of the two openings of the handle, the two alignment tubes each including a first end region attached to the handle and a second end region having a bottom surface that can contact bone, wherein the bottom surface of the body includes teeth.
  • US 2013/213843 A1 discloses an orthopedic fixation system and US 2016/310125 A1 discloses a knotless suture anchor guide.
    • SUMMARY
  • Surgical drill guides are disclosed that allow holes to be drilled into bone at a desired location. Holes are drilled in the bone through referencing holes of the drill guide. A drill guide can be used for guiding a drilling tool (e.g., a drill bit) during formation of one or more holes in bone. A drill guide can be made out of metal (e.g., stainless steel), hard polymeric material, ceramic material, composite material, or any other material. Furthermore, a drill guide can be formed in any suitable fashion (e.g., casting, milling, etc.). Additionally, a drill guide can have various sizes and shapes, depending on the size and shape of a patient's anatomy, etc.
  • Drill guides as disclosed herein allow an implant to be partially inserted after the holes are drilled and before the drill guide has been removed from the surgical location. With the disclosed drill guides, alignment pins are not required. Since a drill guide is not removed until the implant is partially inserted, the location of the drilled hole(s) is not lost. Thereby, methods disclosed herein include the specific exclusion of alignment pins. Various implants can be utilized with the disclosed drill guides.
  • The present invention provides a drill guide according to claim 1.
  • Methods of performing surgery utilizing drill guides are also disclosed herein. In particular, the methods disclosed herein utilize the disclosed drill guides without the need for alignment pins. For example, a method includes inserting a securing member of an implant through a window of a drill guide's alignment tube. Thereby, the securing member is received in a bone hole to attach the implant to the bone while the drill guide is still positioned relative to the bone.

    • Figure 1 illustrates a schematic perspective view of an embodiment of a drill guide;
    • Figure 2 illustrates a schematic perspective view of an embodiment of the drill guide positioned on bone; and
    • Figure 3 illustrates a schematic perspective view of an embodiment of a drill guide and a grasper.
    DETAILED DESCRIPTION
  • Surgical drill guides allow surgeons to accurately drill holes in a bone at a desired location. After drilling a hole, an alignment pin can be placed into the drilled hole to allow the surgeon to find the location of the hole during surgery. When an implant is to be inserted into the hole, the alignment pin is removed to allow the implant to be attached to the bone with a securing member received in the hole in the bone. However, once the alignment pin is removed, it may be difficult for the surgeon to again find the location of the drilled hole.
  • Disclosed herein are drill guides that allow an implant to be partially inserted after the holes are drilled and before the drill guide has been removed from the surgical location. Thereby, alignment pins are not required. Since a drill guide is not removed until the implant is partially inserted, the location of the drilled hole(s) is not lost. Various implants can be utilized with the disclosed drill guides. In an embodiment, an implant can be a compression staple. In an embodiment, a compression staple comprises a shape memory material (e.g., nitinol).
  • Figure 1 illustrates a perspective view of a drill guide 10. The drill guide 10 includes a handle 12 that can be grasped and two alignment tubes 14. Each alignment tube 14 includes a body 16 that defines a drill passage 18, a first end region 20 attached to the handle 12, and a second end region 22 that can contact bone 24. The handle 12 includes two openings 26, and the drill passage 18 of one alignment tube 14 is aligned with one of the openings 26 of the handle 12. The drill guide 10 can be made out of metal (e.g., stainless steel), hard polymeric material, ceramic material, composite material, or any other material. Furthermore, the drill guide 10 can be formed in any suitable fashion (e.g., casting, milling, etc.). Additionally, the drill guide 100 can have various sizes and shapes, depending on the size and shape of a patient's anatomy, etc.
  • The alignment tubes 14 have a substantially cylindrical shape. The second end region 22 includes a bottom surface 32 having a feature that increases traction with the bone 24 to prevent the handle 12 from sliding or moving relative to the bone 24. The bottom surface 28 of the second end region 22 includes teeth 29 that are defined by openings 28. In another example, the openings 28 are substantially v-shaped.
  • Each alignment tube 14 includes two windows 30 that allows access to the drill passage 18 of the alignment tube 14 from outside the alignment tube 14. The window 30 is elongated and extends from the bottom surface 32 of the second end region 22 of the alignment tube 14. In one example, the window 30 is defined by two side surfaces 48 substantially parallel to a longitudinal axis 50 of the alignment tube 14 and an end surface 52 connecting the two side surfaces 48. In one example, the end surface 52 is curved. In one example, the window 30 has a length that is less than one half a length of the alignment tube 14. In one example, each alignment tube 14 includes two windows 30 that are aligned with each other such that the drill passage 18 is accessible from both sides of the alignment tube 14. The windows 30 are spaced approximately 180 degrees apart. In this example, a portion 34 of the body 16 is located between the two windows 30, and each portion 34 defines two teeth 29 and the opening 28 located between the two teeth 29.
  • As shown in Figure 2, the drill guide 10 is positioned on the bone 24 at a desired location. The teeth 29 grasp the surface of the bone 24. A drill bit 36 of a drill 38 is positioned in the aligned opening 26 and drill passage 18, and the drill bit 36 forms a first hole 40 in the bone 24. After the first hole 40 is drilled, the drill bit 36 is positioned in the other aligned opening 26 and the drill passage 18, and the drill bit 36 forms a second hole 40 in the bone 24. The drill 38 is then removed from the drill guide 10, and the drill guide 10 remains on the bone 24 so that each opening 26 and drill passage 18 are aligned with one of the drilled holes 40.
  • As shown in Figure 3, a surgical instrument 42, such as a grasper, is employed to position an implant 46 for attachment to the bone 24. The implant 46 can then be partially attached to the bone 24 by a securing member 44 before the drill guide 10 is removed from the bone 24. The securing member 44 is inserted through the windows 30 of the alignment tubes 14 and into the drilled holes 40 to secure the implant 46 to the bone 24. After the implant 46 is attached to the bone 24, the drill guide 10 can be removed from the bone 24. As the securing member 44 is located in the windows 30, the drill guide 10 can be lifted from the bone 24 without any interaction with the implant 46 or the securing member 44. In one example, the securing member 44 is a compression staple. In an embodiment, the compression staple comprises a shape memory material (e.g., nitinol).
  • As the drill guide 10 remains on the bone 24 during attachment of the implant 46 to the bone 24, alignment pins are not needed to mark the location of the drilled holes 40 because the drill guide 10 is not removed until the implant 46 is partially attached. The alignment tubes 14 of the drill guide 10 are used to mark the location of the drilled holes 40.
  • A method of attaching an implant to bone comprising inserting a securing member of an implant through a window of an alignment tube of a drill guide and into a bone while the drill guide is positioned relative to the bone.
  • Optionally, the method includes removing the drill guide from its position relative to the bone after the securing member of the implant is inserted into the bone. In one embodiment, no alignment pins are utilized.
  • The foregoing description is only exemplary of the principles of the invention. Many modifications and variations are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than using the example embodiments which have been specifically described. For that reason, the following claims should be studied to determine the true scope and content of this invention.
